The loyal Bushies always put politics before national security. And, despite all the claims from the right wing pundits to the contrary, Valerie Plame was indeed a covert agent. Per NBC's coverage:
An unclassified summary of outed CIA officer Valerie Plame's employment history at the spy agency, disclosed for the first time today in a court filing by Special Counsel Patrick Fitzgerald, indicates that Plame was "covert" when her name became public in July 2003.
The summary is part of an attachment to Fitzgerald's memorandum to the court supporting his recommendation that I. Lewis "Scooter" Libby, Vice President Cheney's former top aide, spend 2-1/2 to 3 years in prison for obstructing the CIA leak investigation.
